需求说明: bind下用mysql可以动态加载DNS记录(dlz), 唯一有点不爽的是mysql bind 都需要源码编译安装,
简直吐血, 所以整理下来.
1. mysql 编译安装:
安装依赖包 yum -y install make gcc-c++ cmake bison-devel ncurses-devel 下载mysql wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.35.tar.gz
tar xvf mysql-5.6.35.tar.gz cd mysql-5.6.35 编译安装:
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci make && make install 配置mysql设置权限:# groupadd mysql# groupadd -g mysql mysql# chown -R mysql:mysql /usr/local/mysql 初始化配置:# cd /usr/local/mysql# scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql 注意: 将/etc/my.cnf 改成其他名字,以防冲突 启动MySQl
# cp support-files/mysql.server /etc/init.d/mysql # chkconfig mysql on # service mysql start --启动MySQL 配置用户 # PATH=/usr/local/mysql/bin:$PATH # export PATH # source /etc/profile # mysql -urootmysql> set password = password(‘123456‘) 设置远程访问mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘*‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION; mysql 配置完成 2. bind 编译安装: # ./configure --prefix=/usr/local/bind/ --with-dlz-mysql=/usr/local/mysql --enable-threads=no --enable-largefile --disable-ipv6 --with-openssl=no
//--enable-threads 多线程支持（官网解析是需要关闭）,--enable-largefile 启用大文件支持,--disable-ipv6 关闭ipv6支持,--with-dlz-mysql意思是使用mysql存储域名解析 # make make install 3. 配置bind:# cd /usr/local/bind/etc/ # /usr/local/bind/sbin/rndc-confgen > rndc.conf # cat rndc.conf >rndc.key # tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf 4. named.conf文件
key "rndc-key" { algorithm hmac-md5; secret "mvCUyhyDvNNGywhoVHbSaQ==";};
controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; };};
options {listen-on port 53 {any;}; //开启侦听53端口，any表示接受任意ip连接directory "/usr/local/bind/var";pid-file "named.pid"; //文件内容就是named进程的id allow-query{any;}; //允许任意ip查询forwarders{114.114.114.114;8.8.8.8;}; //设置转发的公网ip};
dlz "Mysql zone" { database "mysql {dbname=dns_data port=3306 host=localhost user=root pass=123456 ssl=false} {select zone from dns_records where zone = ‘$zone$‘ and status = 1} {select ttl, type, mx_priority, case when lower(type)=‘txt‘ then concat(‘\"‘, data, ‘\"‘) else data end from dns_records where zone = ‘$zone$‘ and host = ‘$record$‘ and not (type = ‘SOA‘ or type = ‘NS‘) and status = 1} {select ttl, type, mx_priority, data, resp_person, serial, refresh, retry, expire, minimum from dns_records where zone = ‘$zone$‘ and (type = ‘SOA‘ or type=‘NS‘) and status = 1} {select ttl, type, host, mx_priority, data, resp_person, serial, refresh, retry, expire, minimum from dns_records where zone = ‘$zone$‘ and not (type = ‘SOA‘ or type = ‘NS‘) and status = 1}";};
5. mysql 配置:
create database dns_data
use dns_data
create table `dns_records` ( `id` bigint(20) not null auto_increment comment ‘主健‘, `zone` varchar(255) not null default ‘‘ comment ‘域名‘, `host` varchar(255) not null default ‘@‘ comment ‘记录名称‘, `type` varchar(255) not null default ‘A‘ comment ‘记录类型‘, `data` varchar(255) default null comment ‘记录值‘, `ttl` int(11) not null default ‘800‘ comment ‘ttl(存活时间)‘, `mx_priority` int(11) default null comment ‘mx优先级‘, `refresh` int(11) default null comment ‘刷新时间间隔‘, `retry` int(11) default null comment ‘重试时间间隔‘, `expire` int(11) default null comment ‘过期时间‘, `minimum` int(11) default null comment ‘最小时间‘, `serial` bigint(20) default null comment ‘序列号,每次更改配置都会在原来的基础上加1‘, `resp_person` varchar(64) default null comment ‘责任人‘, `primary_ns` varchar(64) default null comment ‘主域名‘, `status` tinyint(4) default 1 comment ‘0:该记录无效, 1:该记录有效‘, `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT ‘创建时间‘, `updated_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT ‘更新时间‘, primary key (`id`), key `ix_created_at` (`created_at`), key `ix_updated_at` (`updated_at`)) engine=InnoDB default charset=utf8 comment=‘内网DNS记录‘; 6. 插入正向解析数据
INSERT INTO dns_records (zone, host, type, data, ttl) VALUES (‘phpfensi.com‘, ‘www‘, ‘A‘, ‘1.1.1.1‘, ‘60‘);INSERT INTO dns_records (zone, host, type, data, ttl) VALUES (‘phpfensi.com‘, ‘cloud‘, ‘A‘, ‘2.2.2.2‘, ‘60‘);INSERT INTO dns_records (zone, host, type, data, ttl) VALUES (‘phpfensi.com‘, ‘ns‘, ‘A‘, ‘3.3.3.3‘, ‘60‘);INSERT INTO dns_records (zone, host, type, data, ttl) VALUES (‘phpfensi.com‘, ‘blog‘, ‘CNAME‘, ‘cloud.phpfensi.com.‘, ‘60‘);INSERT INTO dns_records (zone, host, type, data, ttl) VALUES (‘phpfensi.com‘, ‘@‘, ‘NS‘, ‘ns.phpfensi.com.‘, ‘60‘);INSERT INTO dns_records (zone, host, type, ttl, data,refresh, retry, expire, minimum, serial, resp_person) VALUES (‘phpfensi.com‘, ‘@‘, ‘SOA‘, ‘60‘, ‘ns‘, ‘28800‘, ‘14400‘, ‘86400‘, ‘86400‘, ‘2012020809‘, ‘admin‘); 7. 插入反向解析数据
insert into dns_records (zone,host,type,data,ttl,mx_priority,refresh,retry,expire,minimum,serial,resp_person,primary_ns) values (‘1.168.192in-addr.arpa‘,‘@‘,‘SOA‘,‘node02.example.com‘,86400,NULL,3600,15,86400,3600,2008082700,‘node02.example.com‘,‘node02.example.com‘); //添加SOA（授权区域定义）记录insert into dns_records (zone,host,type,data)values(‘1.168.192.in-addr.arpa‘,‘@‘,‘NS‘,‘node02.example.com.‘); //添加NS（标记区域的域名服务器以及授权子域）记录insert into dns_records(zone,host,type,data)values(‘1.168.192.in-addr.arpa‘,‘250‘,‘PTR‘,‘node02.example.com.‘),(‘1.168.192.in-addr.arpa‘,‘111‘,‘PTR‘,‘x.example.com.‘); //添加PTR（与A记录相反，将ip转换成主机名，反向解析操作）记录
８． debug 模式下运行 bind 服务# /usr/local/bind/sbin/named -g d 1 -g d 1 是debug的参数 可以查看到后台的日志信息 8. 测试结果:
